Any freestyle lines are acceptable!
If you can't think of any or prefer to read lines, feel free to use these!

Anything that falls in the realm of Angry/Sarcastic characters:

"Wow, this guy's really bad at this talking thing isn't he?" (Sly, sarcastic)

"Shouldn't your first question be..ohhh I don't know, why are my videos so bad?" (Taunting)

"Ha-ha! We know the only reason people watch this show is for ME!" (Arrogant)

"HEY! That was a low blow! Even for you..." (Aggressive)

"Thanks for watching the video loser, if you liked it you can hit that stupid thumbs up button below the video and hit the subscribe button"

"And hey, while you're at it you can check out my videos and my socials too, make sure to follow me on those" (The average speaking voice, No emotion needed)

Anything that falls in the category of a Good person or protagonist:

"Even though I failed, I can still be the greatest ___(input whatever your character is) the world has ever seen!" (confident, excited)

"Hey! I'm in a Youtube video!.. Cool! Umm why am I here again?" (Excited to confused)

"I'm still sore to be honest, this one here really did a number on me" (the average speaking voice, no extra emotion needed)

"Well..I do it for my friends, they've always been there for me when times got rough and I-"(heartfelt, but cut off mid sentence)

"No!.. Why would you even say that? Oh just get on with it.." (flustered, embarrassed)

"Hey guys, thanks for watching! Make sure to hit those like and subscribe buttons before you watch your next video! And while you're at it, I'd really appreciate it if you checked out my work too!"

Random lines that may fit whatever character you're doing an impression of:
